API 5CT Tubing pup joint
The oil casing coupling connects the end of the oil pipe to the coupling body through tapered/flat threads, effectively alleviating the stress concentration problem caused by a single tapered thread connection and reducing the risk of pipe breakage accidents. Technical parameters: Outer diameter range: 42.16mm – 508mm (1.66 "– 20") Material grades: H40, J55, K55, N80, L80, P110, Q125, etc. 68 Execution standards: API 5CT, ISO 11960, GOST, etc Classification of buckle types: NU (10RD flat non thickened type) EU (8RD thickened type) STC (short round thread), LTC (long round thread), BTC (offset ladder thread) and special buckle types 68
